If the disk you are writing too was blank before you started - i.e. it was

to create an approximate mapfile.
ddrescue --generate-mode infile outfile mapfile
It will read the entire outfile and generate a mapfile that assumes that
anything with data is recovered data, and anything with zeros is
unrecovered.
If the destination disk had data on it, however, you can't be sure what is
old data and what is good, recovered data
Unfortunately, while the disk had been formatted, it was only a quick
format, so most of the rubbish on the disk will still be there. :-(
